Space time: The continual question If time moves differently on the peaks of mountains than the shores of the ocean you can imagine that things get even more bizarre the farther away from Earth you travel. кракен ссылка To add more complication: Time also passes slower the faster a person or spacecraft is moving according to Einstein’s theory of special relativity. Astronauts on the International Space Station for example are lucky said Dr. Bijunath Patla a theoretical physicist with the US National Institute of Standards and Technology in a phone interview. Though the space station orbits about 200 miles 322 kilometers above Earth’s surface it also travels at high speeds — looping the planet 16 times per day — so the effects of relativity somewhat cancel each other out Patla said. For that reason astronauts on the orbiting laboratory can easily use Earth time to stay on schedule. https://kra30c.cc kraken onion For other missions — it’s not so simple. Fortunately scientists already have decades of experience contending with the complexities. Spacecraft for example are equipped with their own clocks called oscillators Gramling said. “They maintain their own time” Gramling said. “And most of our operations for spacecraft — even spacecraft that are all the way out at Pluto or the Kuiper Belt like New Horizons — rely on ground stations that are back on Earth. So everything they’re doing has to correlate with UTC.” But those spacecraft also rely on their own kept time Gramling said. Vehicles exploring deep into the solar system for example have to know — based on their own time scale — when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes she added. For 50 years scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites which orbit Earth about 12550 miles 20200 kilometers away — or about one-nineteenth the distance between our planet and the moon. Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon Patla said. “We can easily compare GPS clocks to clocks on the ground” Patla said adding that scientists have found a way to gently slow GPS clocks down making them tick more in-line with Earth-bound clocks. “Obviously it’s not as easy as it sounds but it’s easier than making a mess.”
Of course he said yes to coming back to the series which eventually required him to live in Italy for a few months for filming. hop protocol During production White revealed to Gries that Greg is “very sinister.” That became rather irrefutable by the season’s climax which saw Tanya’s demise orchestrated by her now-husband. Come Season 3 Gries had to rewrite Greg’s backstory again this time drawing from some unlikely sources for inspiration like HBO docuseries “The Jinx” about late convicted killer Robert Durst and the case involving the man who came to be known as the Tinder Swindler. Gries said he was struck by Durst’s “kind of seemingly even keel personality” which served as a model for where Greg was headed someone “who doesn’t really show a great deal of emotion doesn’t seem to get too angry just gets a little bit irritated and is dangerous.” “There’s a bridled rage underneath. And those kind of people I find – at least with respect to Gary Greg Gary – fascinating” he said. And yet while searching for an empathetic way back to portraying his character Gries kept wondering if there was anything still redeeming about Greg. An important “wake up moment” came during a decisive conversation he had with White just before filming in Thailand in which the show’s creator said of Greg in no uncertain terms: “He’s a psychopath.” “And that was it. It was like ‘back to the drawing board.’ And it really did help me” Gries said. The penultimate episode of the series will air on Sunday an evening that thanks to “Lotus” and other shows has again become a night of appointment viewing amid a general move away from binge watching. Gries said he appreciates the shift. “We’re a society that in a weird way doesn’t understand the beauty of waiting. The beauty of the space between the notes” he shared. “If I binged ‘White Lotus’ I’d feel like I just ate too many chocolates. It just wouldn’t be the same. You need to process this.” “The White Lotus” airs Sundays at 9 p.m. EDT on HBO with the episode available to stream on Max. HBO and Max like CNN are owned by the same parent company Warner Bros.

‘A whole different mindset’ Accurate clockwork is one matter. But how future astronauts living and working on the lunar surface will experience time is a different question entirely. kraken ссылка On Earth our sense of one day is governed by the fact that the planet completes one rotation every 24 hours giving most locations a consistent cycle of daylight and darkened nights. On the moon however the equator receives roughly 14 days of sunlight followed by 14 days of darkness. “It’s just a very very different concept” on the moon Betts said. “And NASA is talking about landing astronauts in the very interesting south polar region of the moon where you have permanently lit and permanently shadowed areas. So that’s a whole other set of confusion.” https://kra30c.cc kraken даркнет “It’ll be challenging” for those astronauts Betts added. “It’s so different than Earth and it’s just a whole different mindset.” That will be true no matter what time is displayed on the astronauts’ watches. Still precision timekeeping matters — not just for the sake of scientifically understanding the passage of time on the moon but also for setting up all the infrastructure necessary to carry out missions. The beauty of creating a time scale from scratch Gramling said is that scientists can take everything they have learned about timekeeping on Earth and apply it to a new system on the moon. And if scientists can get it right on the moon she added they can get it right later down the road if NASA fulfills its goal of sending astronauts deeper into the solar system. “We are very much looking at executing this on the moon learning what we can learn” Gramling said “so that we are prepared to do the same thing on Mars or other future bodies.”
Lunar clockwork What scientists know for certain is that they need to get precision timekeeping instruments to the moon.

I think it will be an amalgamation of several different things.” https://kra30c.cc kraken войти Atomic clocks Gramling noted are great for long-term stability and crystal oscillators have an advantage for short-term stability. “You never trust one clock” Gramling added. “And you never trust two clocks.” Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit. As for price an atomic clock worthy of space travel could cost around a few million dollars according Gramling with crystal oscillators coming in substantially cheaper. But Patla said you get what you pay for. “The very cheap oscillators may be off by milliseconds or even 10s of milliseconds” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.” A network of clocks on the moon could work in concert to inform the new lunar time scale just as atomic clocks do for UTC on Earth. There will not Gramling added be different time zones on the moon. “There have been conversations about creating different zones with the answer: ‘No’” she said. “But that could change in the future.”

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards swell network Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny rainforested country. It was one of the most spectacular oil discoveries of recent decades. By 2019 Exxon and its partners US oil company Hess and China-headquartered CNOOC had started producing the fossil fuel.? They now pump around 650000 barrels of oil a day with plans to more than double this to 1.3 million by 2027. Guyana now has the world’s highest expected oil production growth through 2035. This country — sandwiched between Brazil Venezuela and Suriname — has been hailed as a climate champion for the lush well-preserved forests that carpet nearly 90 of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate. While the government says environmental protection and an oil industry can go hand-in-hand and low-income countries must be allowed to exploit their own resources critics say it’s a dangerous path in a warming world and the benefits may ultimately skew toward Exxon — not Guyana.

Starry starry nights For close to 100 years Michelin stars have been a sign of culinary excellence awarded only to the great and good. Georges Blanc the world’s longest-standing Michelin-starred restaurant has boasted a three-star rating since 1981 but this month the Michelin guide announced that the restaurant in eastern France was losing a star. More culinary reputations were enhanced this week when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands while second and third place went to two Hong Kong eateries. You don’t need to go to a heaving metropolis for excellent food however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding Michelin called it “surely the most rural” of its newest winners.
New design revealed for Airbus hydrogen plane renzo In travel news this week: Bhutan’s spectacular new airport the world’s first 3D-printed train station has been built in Japan plus new designs for Airbus’ zero-emission aircraft and France’s next-generation high-speed trains. Grand designs European aerospace giant Airbus has revealed a new design for its upcoming fully electric hydrogen-powered ZEROe aircraft. powered by hydrogen fuel cells. The single-aisle plane now has four engines rather than six each powered by their own fuel cell stack. The reworked design comes after the news that the ZEROe will be in our skies later than Airbus hoped. The plan was to launch a zero-emission aircraft by 2035 but now the next-generation single-aisle aircraft is slated to enter service in the second half of the 2030s. Over in Asia the Himalayan country of Bhutan is building a gloriously Zen-like new airport befitting a nation with its very own happiness index. Gelephu International is designed to serve a brand new “mindfulness city” planned for southern Bhutan near its border with India. In rail travel Japan has just built the world’s first 3D-printed train station which took just two and a half hours to construct according to The Japan Times. That’s even shorter than the whizzy six hours it was projected to take. France’s high-speed TGV rail service has revealed its next generation of trains which will be capable of reaching speeds of up to 320 kilometers an hour nearly 200 mph. The stylish interiors have been causing a stir online as has the double-decker dining car. Finally work is underway in London on turning a mile-long series of secret World War II tunnels under a tube station into a major new tourist attraction. CNN took a look inside.
